Alzheimer’s Disease Symptoms: What is Sundowning?

“Sundowning” is the term used for the changes in personality many Alzheimer’s disease patients experience in the late afternoon/early evening.

Find out how virtually reality is being used to help brighten up the lives of dementia patients. 

According to WebMD, the change in light seems to trigger a cognitive response that gets progressively worse as the hours go on, but remedies itself by morning. Typical symptoms of sundowning include feeling anxious or agitated, disorientated or confused, demanding, angry, restless, and even suspicious. Some patients may start to pace around, shout and yell, and see and hear things that aren’t there.

Around 20 percent of Alzheimer’s patients suffer from some degree of sundowning. Doctors are unsure of why it happens, but it’s more likely to happen if the patient hasn’t had enough sleep, is hungry or thirsty, in pain, or depressed.

There’s no medication to control it but there are ways to try and minimize the effects. Patients can try keeping to a routine, scheduling appointments and visitors in the mornings, eliminating things that may cause sleep disturbance such as drinking alcohol, eating certain foods, napping for too long during the day, and eating large meals in the evening.

A calm environment will help Alzheimer’s sufferers to feel less afraid. Choose neutral colors and bright lighting so they are not upset or confused by shadows. Make sure they are not too cold or too hot. Allow them to do something relaxing in the late afternoon like watching their favorite TV show, listening to music or sitting in the garden. Try to reassure them that everything is OK and if they are likely to wander about, ensure the environment is safe. Find out more about sundowning here.
